What problems did you have?

That ne2k_isa was a big step forward. Before, packet driver loaded "successfully", but showed all FF for the MAC address.

Did anybody try model "rtl8319"? I tried, but packet driver version 3.44 hung.

I use the one from "pktd11.zip".

I use -net nic,model=ne2k_isa -net tap,ifname=tap0 now, but I'm still not satisfied, because there are too many things hard-coded now. I had to turn off DHCP for my real NIC (192.168.0.176), because I had to tell my real router (192.168.0.20) how to find QEMU's subnet (route traffice for 192.168.200.1/255.255.255.0 over 192.168.0.176). That would be OK for one network, but I'm connected to two networks at least (one at work, the other at home).

Here's my current configuration:

Host OS

Broadcom NetXtreme Gigabit Ethernet:
IP address     : 192.168.0.176
Subnet mask    : 255.255.255.0
Default gateway: 192.168.0.20
DNS server     : 192.168.0.20

TAP-Win32 Adapter V8:
IP address     : 192.168.200.1
Subnet mask    : 255.255.255.0
Default gateway: 192.168.0.20
DNS server     : 192.168.0.20

Guest OS

NE2000:
IP address     : 192.168.200.2
Subnet mask    : 255.255.255.0
Default gateway: 192.168.200.1
DNS server     : 192.168.0.20

I would like to remove this permanent route from my real router to get DHCP back for my real NIC. Any idea?
